While targeted to undergraduate and graduate students, this compendium will prove a valuable resource for scholars already familiar with twin studies, as well as those coming to the field for the first time. Here, more than forty experts across an array of disciplines examine twinning and twin research methodologies from the perspectives of biology, medicine, genetic and epigenetic influences, and neuroscience. Chapters provide clear instruction in both basic and advanced research methods, family and parenting aspects of twinning, twin studies as applied across various disease areas and medical specialties, genetic and epigenetic determinants of differentiation, and academic, neurological and cognitive development. The presentation of existing studies and methods instruction empowers students and researchers to apply twin-based research and advance new studies across a range of biomedical and behavioral fields, highlighting current research trends and future directions. Offers unique insights into twinning rates, mechanisms and factors surrounding twinship Provides clear instruction on both basic and advanced twin research methods and study design Features leading international experts in twin biology, genetics, health and psychology Examines findings from recent twin studies across a broad array of health and behavioral studies

Journalist Abigail Pogrebin is many things—wife, mother, New Yorker—but the one that has defined her most profoundly is “identical twin.” As children, she and her sister, Robin, were inseparable. But when Robin began to pull away as an adult, Abigail was left to wonder not only why, but also about the very nature of twinship. What does it mean to have a mirror image? How can you be unique when somebody shares your DNA? In One and the Same, Abigail sets off on a quest to understand how genetics shape us, crisscrossing the country to explore the varied relationships between twins, which range from passionate to bitterly resentful. She speaks to the experts and tries to answer the question parents ask most—is it better to encourage their separateness or closeness? And she paints a riveting portrait of twin life, yielding fascinating truths about how we become who we are.

G is for Genes shows how a dialogue between geneticists and educationalists can have beneficial results for the education of all children—and can also benefit schools, teachers, and society at large. Draws on behavioral genetic research from around the world, including the UK-based Twins’ Early Development Study (TEDS), one of the largest twin studies in the world Offers a unique viewpoint by bringing together genetics and education, disciplines with a historically difficult relationship Shows that genetic influence is not the same as genetic determinism and that the environment matters at least as much as genes Designed to spark a public debate about what naturally-occurring individual differences mean for education and equality

This volume is about an ongoing long-term research initiative led by researchers from the School of Dentistry at the University of Adelaide. The aim of this book is to provide an overview of the studies of the teeth and faces of Australian twins and their families that have extended over more than thirty years.

A 2022 Choice Reviews Outstanding Academic Title Takes the first in-depth look at the New York City adoption agency that separated twins and triplets in the 1960s, and the controversial and disturbing study that tracked the children’s development while never telling their adoptive parents that they were raising a “singleton twin.” In the early 1960s, the head of a prominent New York City Child Development Center and a psychiatrist from Columbia University launched a study designed to track the development of twins and triplets given up for adoption and raised by different families. The controversial and disturbing catch? None of the adoptive parents had been told that they were raising a twin—the study’s investigators insisted that the separation be kept secret. Here, Nancy Segal reveals the inside stories of the agency that separated the twins, and the collaborating psychiatrists who, along with their cadre of colleagues, observed the twins until they turned twelve. This study, far outside the mainstream of scientific twin research, was not widely known to scholars or the general public until it caught the attention of documentary filmmakers whose recent films, Three Identical Strangers and The Twinning Reaction,left viewers shocked, angered, saddened and wanting to know more. Interviews with colleagues, friends and family members of the agency’s psychiatric consultant and the study’s principal investigator, as well as a former agency administrator, research assistants, journalists, ethicists, attorneys, and—most importantly--the twins and their families who were unwitting participants in this controversial study, are riveting. Through records, letters and other documents, Segal further discloses the investigators’ attempts to engage other agencies in separating twins, their efforts to avoid media exposure, their worries over informed consent issues in the 1970s and the steps taken toward avoiding lawsuits while hoping to enjoy the fruits of publication. Segal's spellbinding stories of the twins’ separation, loss and reunion offers readers the behind-the-scenes details that, until now, have been lost to the archives of history.

A New York Times Notable Book for 1998 Critical acclaim for Lawrence Wright's A Rhone-Poulenc Science Prize Finalist "This is a book about far more than twins: it is about what twins can tell us about ourselves."—The New York Times "With plenty of amazing stories about the similarities and differences of twins, Wright respectfully shows, too, how their special circumstance in life challenges our notions of individuality. A truly fascinating but sometimes spooky (Mengele's experiments with twins at Auschwitz figure among Wright's examples) study."—American Library Association "Like so much of Wright's work, this book is a pleasure to read. Because he writes so well, without pushing a particular point of view, he soon has you pondering questions you have tended to comfortably ignore."—Austin American-Statesman "Informative and entertaining . . . a provocative subject well considered by a talented journalist."—Kirkus Reviews
